Hi Team,

We are trying to integrate using VXML and GRXML in Genesys with uniMRCP server configuration. We are facing issue with this integration.

1. How gxml and uniMRCP will communicate. Is there any deployment steps are available in uniMRCP side.

2. In VXML grammar tag ,i have added src="builtin:grammar/names?projectid=3c5188cc-baee-4c37-94ca-e4ae2ae6e5fb.

What is the projectid denotes ,it's GDF agent name (or) GDF agent-id ?

3.Any configuration required for grxml in uniMRCP(umsgsr.xml / umsgdf.xml) side to make it work in Genesys & GSR/GDF.

4. Please find the grxml code,how this will work in UniMRCP.

======================================================================

External GRXML code:

---------------------

<?xml version="1.0" encoding="UTF-8"?>
<grammar mode="voice" root=" names " version="1.0" xml:lang="en-US" xmlns="http://www.w3.org/2001/06/grammar">
<meta name="scope" content="builtin"/>
<meta name="projectid" content="3c5188cc-baee-4c37-94ca-e4ae2ae6e5fb"/>
<rule id="names">
<one-of>
<item>call Steve</item>
<item>call John</item>
<item>dial 5</item>
<item>dial 6</item>
</one-of>
</rule>
</grammar>

==============================================================

VXML code :

--------------------

<form id="InputKB">
<property name="inputmodes" value="voice" />
<property name="bargein" value="true" />
<block name="InputKBP0">
<prompt gvp:langexpr="AppState.APP_LANGUAGE">
Thanks for calling, Please say or enter your mail id.
</prompt>
</block>
<field name="InputKBField" slot="out">
<grammar mode="voice" src="builtin:grammar/transcribe?projectid=3c5188cc-baee-4c37-94ca-e4ae2ae6e5fb" />
<property name="interdigittimeout" value="3s"/>
<property name="termchar" value="#" />
<property name="timeout" gvp:expr="AppState.timeOut"/>
</field>
<filled mode="all" namelist="InputKBField">
<assign name="AppState.Result_Out" expr="InputKBField" />
<assign name="AppState.InputKB$" expr="InputKBField$" />

</form>

Thanks

1.there is no need to deploy anything in unimrcp server side for SRGS grammar. So you can find additional information by refering this link https://www.w3.org/TR/speech-grammar/

2.project-id is ID associated to the corresponding Dialogflow agent. So you must create project in google cloud console to use dialogflow or bind dialogflow to any project otherwise you can't use gdf

if you want to use srgs external grammar you must set src to path of this grammar

if you want to use srgs grammar in vxml you only need to write grammar in grammar tag inside <field> element in vxml.

Thanks

Hi Kocharyan,

Thanks for the immediate response.

In Vxml code , I am using External grammar ,How to define the path?

Anything i need to pass as query parameters in the path.

My External grammar is located in C:/usr/Project folder. Can i give simply this path in src (or) i need to pass project ID as a query string.

<grammar src="C:/usr/Project"/> -- i mentioned only grammar path

<grammar src="C:/usr/Project?projectid=3c5188cc-baee-4c37-94ca-e4ae2ae6e5fb> -- I mentioned grammar path and GDF project ID.

In the above two examples ,which one is correct.

Another question, How this VXML and GRXML is communicated by uniMRCP ?

Can you please clarify me this communication / Architecture part.

In the below example , I have mentioned external grammar and added two <meta> tags. These tags are correct ? Or i need to add anything specific to UniMRCP. Please clarify me.

Thanks

Karthik

Hi Karthic,

To start off, no specific configuration is required to make Genesys PureConnect and/or Engage (GVP) work with UniMRCP Server. All you basically need is to add the UniMRCP Server (IP address and port 8060) as an ASR and/or TTS resource for Genesys.

Now, narrowing down the scope, when it comes to the use of UniMRCP with Google Dialogflow, you may need to specify some Dialogflow parameters in your VoiceXML application running on Genesys. There are a few alternate ways of specifying those parameters:

https://docs.unispeech.io/en/ums/google-cloud/dialogflow/usage#h-413-specifying-vendor-specific-parameters

MRCP header field Vendor-Specific-Parameters
query attributes to built-in grammar
meta parameters in SRGS XML grammar

All the above options can be used interchangeably in most of the cases, regardless of the actual integration.

You may get started with the following application:

https://github.com/unispeech/ums-sample-apps/blob/main/voicexml/gdf/TestDialogflow.vxml

Hi Arsen,

Thanks for your response. I have attached my VXML,GRXML and UniMRCP logs in the zip file. Whenever I called External GRXML from VXML , I am getting Completion-Cause: 004 grammar-load-failure . We are using Genesys Voice platform (GVP) and GDF. Not able to attach it , so copy pasted the log and code.. We are using MRCPv2

External Grammar :

<?xml version="1.0" encoding="UTF-8"?>

<one-of>
<item>call Steve</item>
<item>call John</item>
<item>dial 5</item>
<item>dial 6</item>

<item>correct</item>
<item>Yes</item>
</one-of>
</rule>
</grammar>

Hi Karthik,

HTTP grammar reference is currently not supported. You should use either a built-in or an inline SRGS XML grammar in your VXML.

For example:

<rule id="transcribe">
<one-of><item>blank</item></one-of>
</rule>
</grammar>
